We have been fighting on reducing trees and the deteriorating weather. But what about thousands of speed breaker that are responsible for increase in fuel consumption, pollution generation in Bangalore and wastage of revenue to the person, city, state and country. On a rough calculation the city loses due to speed breakers:

Assumption that every kilometer there are only 2 speed breakers – While we all know the count is much higher. Calculation taken only for cars if we include other modes it would be much higher. Also all have been assumed as petrol vehicles with average consumption of 13 Km per liter in city

43360200 Litres of fuel every day

2601612000 Rupees calculated @ 60/- per liter

Kg of CO2 generated per litre of petrol (Diesel is 10% + on petrol) is 2.31 per Kg

Additional pollution generated due to speed breaker in a day 100162062 Kg
